IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 153,432, dated July 28,1874; application filed October 13, 1873.

To all whom it may concern:

Be it known that I, FRANK W. FREUND, of Denver, Territory of Colorado,have invented certain new and useful Improvements in Breech-LoadingFire-Arms; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification, in which Figure 1 is a sideview, showing a portion of the arm in section in the line a; m, Fig. 3,and a portion in elevation. The fire-arm appears not cocked. Fig. 2 is aperspective View of my improved sear. Fig. 3 is a top view of thetrigger-box or bottom piece of the st( ck with the improved sear andsear-spring and other trigger mechanism, the main spring of the hammerbeing broken away in order to not have it hide the said mechanism. Fig.4 is a perspective view of the improved scar and forked spring in properrelation to one another, but detached from the arm.

To enable others skilled in the art to understand my invention, I willproceed to describe the same with reference to the drawing.

My improvements relate to an improved slotted scar and forkedsear-spring, whereby I am enabled to put double-set triggers inbreech-loading guns which have the lock in the center and a low hammer.

In the accompanying drawings, A represents the sear. It is made of onesolid piece of steel cut out at the center, as at a, to allow theset-triggers b b to work in between the inner sides formed by cuttingout the metal to form the opening a. The sides of the scar are shapedlike the rocker of a cradle, and the rear under portion of each is cutaway to form a detent, f, for the end of the sear-spring, as shown at c.This sear is fastened to the trigger-box or bottom piece J of the stock,so as to vibrate, by two screws, 61 cl, one on each side, in order thatit may work with an equal bearing on each side as the set-triggers b bstrike at points between these screws. The sear is also made so that theset-triggers are independent of it; these triggers therefore can be andare attached to the trigger-plate g, and 9 this plate being confined byonly one screw, h, great convenience for taking these triggers out foroiling, or any other purpose, is afforded, it not being necessary, as inmany cases, to take the whole lock apart for this purpose. B representsthe sear-spring. It is forked as at t z, and its respective forks t fitabove the respective detents f, which are near the screwpivot holes (1of the sear, as shown. The opening between the forks of the spring Ballows room for the set-triggers to work up and down, and it alsopermits the spring m of the rear trigger b to be placed above it, andits front end to pass down between its forks behind the detent n of saidtrigger; and it also permits the angular spring m, which operates uponthe forward trigger b, to be extended to the detent n of said trigger,and to play up and down. without obstruction between its forks. Thissear-spring, by being set in detents near the pivots of the sear, is notsubject to great leverage strain, and therefore is not liable to bebroken easily.

It has long been a serious complaint against the single-set trigger ofthe most approved arms that when it is set fine it is not safe, and ifconstructed to be set otherwise it is too hard to operate for fineshooting. This complaint my improvement entirely obviates withoutaltering the approved style of the arm.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The scar A, open at its center, as at a, and constructed withindependent detents ff, whereby it is adapted for use with a forkedspring, the set-triggers b b, and the hammer, substantially as and forthe purpose described.

2. The sear-spring B, forked as at i i, in combination with the sear A,whereby these parts combined are adapted for use with the set-triggers bb and the hammer, substantially as and for the purpose described.
